Given cyclohexane in a chair conformation, substitute two of the H labels with methyl and propyl to construct the more stable conformation of cis-1-methyl-2-propylcyclohexane. Use the numbering provided on the ring.
Cyclohexane is more stable in its chair conformation. In chair conformation of cyclohexane, two types of groups are present at each carbon atom. They are axial groups and equatorial groups.
If two substituents are cis to each other then they are in up, up (or) down, down to each other in chair conformation.
Bulky groups present in equatorial positions will make the chair conformation most stable. If the bulky groups present in axial positions, then 1,3-diaxial interactions will make the chair conformation less stable.
The possible chair conformations for the given cis-1-methyl-2-propylcyclohexane are,
Ans:Thus, the most stable chair conformation of cis-1-methyl-2-propylcyclohexane is,
